I realize everyone on here has different electrical req's with how they camp. I don't fulltime and don't camp in the winter and have minimal electrical req's. I dry camp don't watch TV or play on the internet, so basically some lights, refer, WH, and water pump. He kept talking about real world experience and did 20 amp discharge test down running MV's to 8 amp tests and then concluded that LI was cheaper over the life cycle of battery usage. What I would have rather seen was low amp draws \"real world\" how I use my batteries and how long each battery would last. At $900/ battery for lithium and $90 for 6v flooded that is 10 times the cost. Will the LI's last 10 times longer to recover the initial cost?

What about hot weather testing? Damage on LiFePo4 starts at 86 f, and they should not be charged when the temperature is 113 f.
Lead acid batteries don't like prolong high temps either. Definitely shortens their life.
True, however lead acid can be used at 140 f and charged at 120 f--that's a far cry from 86 to 113 f for LiFePo4. There is no question that higher temperatures reduce lifespan.
However, does the BMS for the LiFePo4 shut down charging at 113 f?

Lasts four times as long?
Warranty half as long?
Ever see Herb's face when Jennifer detailed what she was going to let her date do to her?
The Show was a masterpiece of BS sales parody

I think the energy advantage has to do with the high discharge rate of LFPs but not clear on that.
IMO a good case for LFPs can be made for some scenarios without all the silly stuff.
